Almost always, yes.

Or, if you write it in Rust, it'll get merged into gst-plugins-rs :)

There are some checklist items here

https://gitlab.freedesktop.org/gstreamer/gstreamer/-/blob/main/subprojects/gstreamer/docs/random/moving-plugins

but it's not really a superwell defined process. The technical / code
style bits are usually easy, but then there's also a subjective "does
it seem ready and in good shape" bit to it, and a question or whether
the plugin API is good and will likely stand the test of time. Does the
plugin seem actively used/maintained? Are multiple GStreamer developers
familiar with it and can help maintain it?  Is there a group of
external contributors who is actively using and contributing or
maintaining it? Are people using it successfully, what issues, warts,
problems have they run into that should perhaps be fixed before a move,
etc.

On the upside there's probably no issue with licensing/patents here on
the plugin side.

Cheers
